Omega Gideon Shadow – UMP Pistol – Atlantic Firearms

    There have been three things that have kept me from considering a Heckler & Koch UMP clone build. First, rather than a more typical three-lug muzzle attachment system, the UMP’s barrel comes standard with the mushroom-esque flange that only a few silencer manufacturers have been able to master. Second, the UMP operates on a direct blowback system rather than the roller-delayed action found in its older sibling the MP5. Lastly, is price. Ok, let’s face it, nothing H&K is going to be inexpensive – but with manufacturers like Zenith making H&K style pistol caliber carbines in the sub $2000 category, these guns are becoming more affordable. However, Omega has just announce the Gideon Shadow – a UMP that is entering the relm of obtainable for the masses.

    On the positive side, the UMP is lighter, features a last round boot hold open and with the addition of a kit, calibers can be changed in a matter of minutes. The Gideon Shadow is a sharp looking gun that includes a pistol stabilizing brace from SB Tactical.

    These are currently showing sold out at Atlantic Firearms with more due in stock in a few weeks. MSRP is $2,399.

No other parts of the gun have to be changed or replaced to change the caliber. The pistol has a 7.87″ barrel length weighing in at about 5 lbs. total weight, magazine unloaded.

With the front finger guard it allows for a two point sling attachment.
